For the skaters out there, some parts are smooth some parts are not. Unless you are a more advanced skater with super squishy wheels, its not the best.
Lots of people and dogs out on this spring day enjoying the sun and fresh air. The streets are well-marked, every major road crossing has lights for pedestrians. Large trees, several parks, beautiful path!
We ride this one routinely. Flat hard packed gravel with a slight crown. Low traffic and an overall quiet setting. It is open all the way through including past the golf course, there are just gates to keep cars out.
I had just come from downtown and was wondering how far the path on the other side went. I then saw a sign to a park and followed it and I was pleasantly surprised and followed it to the end. I love it, if you get a chance check it out!
What a stunning trail! Absolutely gorgeous . We are gravel bikers so the terrain felt amazingly smooth with some bumps here and there— but they are marked. The elevation gain from Banks to midpoint (Stubs state park) is 1000 feet. It’s a slow grade incline and manageable on a good bike. Oregon takes such good care of its state parks and trails. Bravo!
I rode between the west end and St.John’s Rd…a Saturday…my first time on this trail. This part of trail is in excellent shape yet directional signage is poor, non existent or damaged and as a result I ended up on one dead end spur where it appeared I stumbled into some drug dealing or use…did a quick U turn! There are also no mile markers and the trail changed names 3 times on this section: Burnt Bridge, Ellen Davis and Discovery trail. More confusion! That said I’ll attempt the entire route soon and provide an updated review then.
As the description indicates, this trail is only partially paved, a lot of it has large, loose gravel adding significant time and effort to the pedaling. Additionally, the hill climbs are much steeper than any rail-trail; I'd guess only about half was actually a former rail line. We started in Scappoose and went all the way to Vernonia Lake, ending at the same place as the Banks-Vernonia trail but much more tired! However, the trail has the same beautiful scenery as can be expected in this part of the country--just plan for a longer, more arduous ride!
We stayed at Columbia River RV and rode from the RV Park to the first section of Marine Drive Trail - I saw that the I-205 joins directly there so we took it south. I saw that it went over the two bridges of the Columbia river so we gave that a try. Wow. It is a bike path in the middle of the bridge with northbound traffic whizzing by on one side and southbound on the other. The noise!! LOL The path is barricaded by a concrete wall on both sides and then a metal guard rail on top of that. So honestly felt safe enough. We did the first mile over the first bridge and then turned around. It was an experience to say the least. (We are both 79) Then we continued south on the trail for about 6 miles. I like this kind of trail - kind of urban-lots to look at. Some industrial/one section of beautiful older houses. We didn't get to any homeless but in the distance I could see a big tent setup. We have ridden lots of trails with homeless and never been bothered but I know it does bother some people. Sometimes we stop to talk with them and all have a sad story. I would definitely ride this again if in the area-we are from AZ just roaming in our small RV with ebikes on the back staying out of the AZ heat.
Day #1 We started at the Pisgah Trailhead Parking and rode north. I think a lot of this was asphalt at some point but most of it has deteriorated to hard pack dirt and small gravel. There are short sections where the asphalt returns. Its about 5 miles to the Ruley Trailhead-we rode another 3 and then turned around. It was gorgeous. Huge tree canopy the whole way. Lots of ferns/heavy moss on trees and we saw a deer on the bike path.
Day#2 - parked at the same place and rode south. The terrain is much more open and as you go south the pavement returns. It's only about 4.5 miles to the end of the trail so we rode Dike Road for several miles. No traffic and at one point you can ride to the top of the dike and see the moored boats and floating houses.
We are just roaming around in our small RV with the ebikes on the back - staying out of the heat of AZ-so I'm glad we got to do this trail and we love all trails pretty much but I wouldn't go out of my way to do it again.
We rode from the Senator Mark Hatfield parking in Mosier west toward Hood River. 1st 1.8 miles gradual uphill. Fun to go thru the tunnels. Stunning views. Fun to be so far above the river. Then downhill towards Hood River. Total one way 4.8 miles.
We started in Parking lot#3. Glad to have the traillink map-it was fun cruising around all the loops - so much better than a straight path. Every section was different. Beautiful scenery - saw a big eagle nest with Mama in it/a huge lilypad pond. We did 10miles but this could easily be at least a 20mile trail. Just go in reverse and mixup the loops. Totally enjoyable and I would use this all the time if I lived close to it.
